1  Introduction 

 

The FINE-SPRAY gun 

W 3/FZ-Duo

 is designed and constructed for finest application of thin materials 

f.i. release agents, colours or other fluids of low viscosity. Depending on air cap this spray gun sprays in 
a  round-  or  flatspray.  Spray  guns  are  precision  tools.  Always  keep  clean  and  observe  minimum 
instructions to maintain a long useful life of the gun.

Trichlormethane or Methylen Chloride i.e. agents of the group of chlorinated hydrocarbons.  

 

These chemicals may react with aluminium, anodised or zinced parts. The chemical  

 

reaction may be explosive. 

 

2.3  Warning against Danger 

This operating manual warns users of operations which may put their health at risk. The warnings are

3  Function Description 

 

Your  new  spray  gun 

W  3/FZ-Duo

  has  been  thoroughly  tested  before  leaving  the  factory.  No  more 

adjustment  is  necessary  prior  to  setting  up  spray  operation.  If  fluid  output,  however,  requires  to  be 
regulated individually, apply needle regulator (24.1) and counter nut (23.1) for quantity of fluid flow. To 
spray with a spray gun definite volume of atomising air and a definite pressure of materials is needed. 
The needle will be opened by activating the trigger and the material flows out of from the nozzle. The 
air pressure atomises the material and forms it to a jet. 
The needle function is: Opening by trigger and closing by spring force.
